What query_table does on MariaDB Reader MCP Server

AI agents call query_table to retrieve information from MariaDB Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why query_table needs a policy

This tool retrieves data from a MariaDB table without modification or deletion. The explicit mention of limited row returns mitigates risk by preventing bulk data exfiltration. Combined with sibling tools (get_table_schema, list_databases, list_tables) that are all schema-inspection utilities, query_table is clearly a read-only operation. No code execution, data modification, or irreversible actions are involved.

From the tool's definition Tool description states '특정 테이블에서 데이터를 조회합니다 (제한된 행 반환)' which translates to 'Query data from a specific table (returns limited rows)'. The term '조회' (query/retrieve) indicates read-only data retrieval with row limits preventing excessive data extraction.
